A sexual act involved in the bedroom between a man and a woman. The man inserts his penis into the vagina, before removing it and inserting it into the anus, then back to the vagina, then back into the anus and so on and so forth until he cums.
The term derives from economics, 'a long-term recession', because many couples now resort to more compelling sex moves due to personal financial circumstances.
Not to be confused with a Triple-Dip Recession, which involves insertion into the mouth as well.

"We had so many financial problems after I lost my job, I had to give her a Double-Dip Recession until I cummed in her arse"
